Application Sled November 8.1902. Serial Re 130.605. 5c mode!) 1'0 all whom it muy concern:

Be it known that I, THOMAS E. lHALL, acitizen of the United States, residing at Chicago, in the couutyofCook and Stateot Illinois,have invented a certain new and useful Improvenient in Medicamentflnjectors, of which the following is a specification.

The object of this invention is to construct an injector for the application of medicament xo in the form of dry powder to passages ofthe human body'nnd have the application propcrlg made and under conditions to obtain the most beneficial results and so ns to insure the dfscharge of the powder ivithout beingluiupy; and the invention consists in the features-of constructions and combinations of parts hereinafter described and claimed. A

In the drawings, Figure 1 is a side elevation of the injector of the invention; Fig. 2,

:o a central longitudinal section of the same 3o having a rim or flange b', which when the cap or cover is in place abnts against the edge of the rim a' aroundl the opening. I

The opposite side of the body or lwall a is fullyopen,and across this opening is stretched 35 acover c,of any suitable material, constituting the movable section of the bellows or blower. The cover c is attached, as shown, v to the body or wall by entering the Yedge of the cover into a clasp a?, formed by turning 4o the edge of the body or wall over the edge of the cover. The- `ver c has at its center a disk c', with a turned peripheral edge or rirn c2, and against this disk within the edge or rim abut'sthe end of a spring (l, the other end' 45 of which rests ou the rim a of the body or wall. This spring serves to hold the cover c under tension and permitsl the cover t0 be pressed inwardly to eject or force ont the wder or other material within the chamber 5o of the bellows or blower, and with the release of the force for xnrwardly pressing the cover the spring acts and returns the cover to mal position. v

The body` orvwalhthe cap b on one side the cover c onV the other side, inclose a ci ber for the reception of the powdered met ment, and the medicament is supplied -tt chamber by removing the cover b and 'e1 ing the medicamentthrough theopening, when the required amount of medicame entered the opening is closed by the e1 A nipple e leads through the body or wi the bellows or blower and,'as shown, i: cured in place by a flange e' on its inne: and a collar ez around its body adjacei the outer face of the bod)- or wall. The ple has slipped thereunto one end of a f, preferably of rubber or other flexible terial, but which could be of suitable rigii terial. The other end of the tubefis sli or entered onto the end of the stein a discharge-nozzle having a discharge g', with a fine perforationl in its disci end. The discharge bulb is of a cc shape, forming a cliainlr on the it against .the wall v 'which the powdered icament will b` ,riven by the force c discharge for the impact of the pt against the wall of the chamber to breI and destroy any lumps or adhesion of th ticles, thereby insuring the disehargei powdered medicament at the. place'of i cation in a condition not to' cause irri from lumps or adhesion of the particle also preventing the stoppage of the disc orifice or perforation by lumps or adi particles, thus insuring the operation v1 injector in discharging the particles pn and have the application thereof to th to be treated an efficient and reliable t VThe discharge-noz zle is surrounds( tube h, preferably of metal or other su material, which tube extends beyond tl of the nozzle, and its outer end h' is', as s cnt on an incline, so as to facilitate the ing of the tube into the vagina or'othc Ysage of the body to be treated and to l the discharge of the medicament to rected onto the diseased portion thati treated. The interior diameter of the is as large as' the "exterior diameter bulb at its largest paris5-and the inte the-tube forward of the ehargebulb forms a cbamberinto which the medicament spreads from the dischargebrie'e e the bulb, to be discharged ina sprayed o. `.howered condition onto the place o f application.

The tube It nt its inner end isclosed by a cork or stopper kof anv suitable material,

entered into which is a bushing i", through which and a head F, against which thecork abuts, the tube f passes and. as shown, `tbe hole for the passageoi'- t'e tube fthrough the cork, bushing, and head is of a greater diameter than thc diameter of the tube, leaving a passage f around tite tube, so as to prexfent the forxuiugof a vztcznm within the tube 1i, by which the suction of the bcllo'ws'or blowers on tbe outward movement of the cover would draw or suck the. discharged medicament back into the tube h and destroy its deliver) tn the part to be treated.

vThe medicament, preferably in the form of a fine powder, is placedV in the chamber of the bellows or blower b5' removing the cap, aud when filled to the extent required tite cap is replaced andthe injector or iustrument is ready for use, in use the tube h is entered into the vaginal passage or other passage of the body where the treatment is to be applied, and when the proper point is reached the cover c is pressed inwardly, discharging a quantity of the powdered medicament from the chamber of the bellows orblower through the nipple e, tube f, and stem g of the discharge-nozzle into the chamber of the bulb g' of the nozzle to paxs therefrom through the discharge orifice or perforation into the tube h and be directed therebgand discharged at the place of application If more than one discharge of the medicament isrequired at one operation, the bellows or blower can be turned upedgewise,as shown in Fig. 3, allowing the powder to fall down after each move- 'ment of the covers for the next advance of the cover to discharge and apply a further quantity of the medicament, and for the purpose of obtaining several discharges wit-hout removing the tube g a fertible tnbef is preferred; but where only onedischarge swanted the tube fcan be of some rigid material.

After tire contentsof the chamber'of the bellows or blower have been discharged it can be refilled by removing the cap'.

It. will be seen that:- with the injector or instrument of the present invention the application of powdered medicament within the passage to be treated at the point of application for the medicament is assured in a reliable' manner, that one or more discharges canbe obtained without the removal of the 6o distribnting or applying tube, that danger I rom lumps e: adhering particles of the der is overcome, that thevdistributing o plyin'g tube @gens the passage for the r tionof the mdicament, that the pom medicament is. discharged in a shower sprayed form directb on the diseased vthat suction sannottake place to with the'medicarnent when once discharged that the operation of the injector or i! men-t does nca require any special ski cept in locamng the diseased part aud erly directing the tube to discharge the all of which makes the injector or instrl very desirable and applicable for use in ing diseases ci the vagina, for which pv: itis specially designed and for internal nient of other passages.

What I rerard as new, and desire to: by Letters Patent, is-

1. In a medicament-injtor, the cou tion of a distributing-tube, a closure in into the rear end of the tube, a flexibl passing entirely through the closure ar jceting inwardly therefrom, a dischar'g1 zl'e inserted into the inw'ardLv-proj'ectil of the tlexibe tube, and a bellows or l having a chamber for containing a n? ment preparation connected with thef tube exterior of the closure, snbstanti described.

2. In a medicament-injector, the co tion of a discharge-tube, a closing-plug ed to be slipped into one end of the dist tube, a flexible tube passing throu plug, projeetinginwardly therefrom, charge-nozzleinserted into the inward jecting end ethe flexible'tube and pi at its free end with an enlarged couediscbargebnib, anda bellows or blo terior of the discharge-tube. aud cot with the tiexible tube, 'substantially scribed.

3. In a medicarneutdnjector, the cc tion oi a discharge-tube having its e end cut on an incline, a closure inset' the'opposite end of thedischarge-tube ble tube pessing entirely through sure and projecting inwardly therefrol chargenozze inserted into the projet of t-heexible tube consisting of a i bular stem provided on its end wit-l larged dischargebulb, and a. bel blower, adapted to contain a' med preparation, exterior of the disc'hai and connected with the exible tul vstantially'as described. v
